They found that they could not improve the signal-to-noise ratio of the first telecommunications satellite.

他们发现无法提升第一颗通卫星的。

Plus, the goal isn't to eliminate noise completely but  to get the best signal-to-noise ratio possible.

另外，我们的目标不是完全消除声，而是获得尽可能最佳的。

So it's just like, you have to save the energy and watch the signal-to-noise with these people.

所以这就像，你必须节省精力并与这些人一起观察。

I would just say, rejecting paths with poor signal-to-noise ratios left us with.

我只想说，拒绝差的路径给我们留下了。

And so the signal to noise ratio is very different.

常不同。

So not being able to reduce the signal or increase the signal-to-noise ratio, the noise

因，无法降低度或提高，音依旧存在。

One of the things if you sort of drop noradrenaline onto neural circuits, it will very much increase what we call the signal to noise.

如果你把去甲肾上腺素加入神经回路中，它会大大增加我们所说的。

One thing is, we've got this, after rejecting paths with poor signal-to-noise ratios, we were I think we can shorten that just a little bit.

一件事是，我们已经得到了这一点，在拒绝了较差的路径之后，我认为我们可以稍微缩短一点。

After rejecting paths with poor signal-to-noise ratios, We were left with 678 velocity measurements of waves with 7.5 second periods and 891 measurements of 15 second waves.

在拒绝较差的路径后，我们剩下 678 个 7.5 秒周期的波速度测量值和 891 个 15 秒波的测量值。

To put it all more formally, predators need to maximise their perception of signal (their proposed meal) from the noise (the general environment); the goal of prey is to minimise that same signal-to-noise ratio.

更专业一点来说，捕食者需要将自己感知“”（他们可能的食物）的能力在音中（一般环境中）最大化；而猎物的目标是将相同的降至最低。

So we can boil this one down to rejecting paths with poor signal to noise ratios left 678 velocity measurements of 7.5 second waves and 891 of 15 second waves.

因，我们可以将这个问题归结为拒绝较差的路径，剩下 678 个 7.5 秒波的速度测量值和 891 个 15 秒波的速度测量值。

Compared with traditional TIA, the experimental results show that the proposed TIA circuit has a high bandwidth, low noise, high signal-to-noise ratio, good dynamic performance and can meet the needs of optoelectronic conversion.

与传统的TIA相，实验结果表明，所提出的TIA电路具有高带宽、低声、高、良好的动态性能，并且能够满足光电转换的需求。

And they would take that—1946—and they would take that telescope technology that radio astronomers had developed, and they would use that to see if they could improve the signal-to-noise of the satellites that they were seeing.

于是，他们采用了——1946年——以及射电天文学家所研发的天文望远镜技术，试图利用这些技术来提升他们所观测卫星的。
